'MEANS FORYEORMNG CONCRETE COLUMNS.

Application filed November 20, 1916.

To @ZZ whom t may concern:

Bc it known that we, JOHN C. EBERLE and BENJAMIN S'roncii, citizens of the United States, and residents of the city of New York, in the county of Kings and New York, respectively, and State of New York, have invented certain new and useful Improvements in Means for Forming Concrete Columns, of which the following is a specilication. Y

rihe present invention relates to improvements in molds for forming concrete supporting-columns.

Molds for this purpose have heretofore been generally in use. All ofthe same, however, as far as known, have a number of serious defects.` One of these defects consists in that the molds are not properly supported in position for the molding operation. On the other hand, if supporting means are provided, the. constructions are to such an extent complicated that they are impracticable for ordinary building work.

The main object of the present invention is to provide a column-mold that is adapted to be supported by simple and inexpensive means, thereby obviating the dilhculties ex.- perienced with constructions of this type heretofore in use.

Another object of the invention is to so construct the. supporting means that it can be easily taken apart after the molding operation, and used over and over again.

.A further object of the invention is to generally simplify and improve the construction of' column molds, and to produce a commercial article, that is to say a device which can be manufactured at a cost that is not beyond that of those now generally adapted.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement, and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of `Specification of Letters Patent.

Patented J une 26, 1917. serial ne. 132,370.

the invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a concrete column-top, formed by means of the mold herein disclosed; Fig. 2 is a central vertical section taken through the top part of the mold; Fig. 3 is a top plan view of the mold and the elements cooperating therewith; Fig. 4.- is a central vertical section taken through a detail of construction, on a larger scale; Fig. 5 is a top elevation of the detail shown in Fig. 4f; Fig. 6 is a front elevation of a portion of the mold; and Fig. 7 is a section taken on line 7 7 of Fig. 6.

Referring now to the drawings, the numeral 10 indicates a mold or casing for the top or head of a round column. This mold is made of a plurality of longitudinally separable. sections, for instance two sections 11 and 12, the edges of which overlap, as clearly shown at 13. The sect-ions are united by screw-bolts 14 or other fastening means. The mold is made of sheet iron or similar 'materiah and is provided at its upper edge with an outwardly extending annular flange 15. For the purpose of supporting this mold, there is an ordinary scaffolding 1o built. This scaffolding includes horizontally extending beams 17, which are so arranged as to form a square, into which the mold is fitted. In the corners of the square are located struts 18, which connect intersecting beams 17. Above the upper faces of the beams 17 and struts 18 projects, within the square, a ring 19, of any suitable cross-section. In the case illustrated the ring 19 is of a cross-section corresponding to that of an angle-iron, the horizontal fiange 20 of which projects inward, that is to say toward the center of the ring. The ring is supported upon the scaolding by a plurality of blocks 21. Each of these blocks is, preferably, made of' two sections, denoted by the numerals 22 and 23. The sections 22 may be of any suitable configuration and are attached to the beams 17 or struts 1S, as the case may be, by nails 241 or otherwise. The vertical flange 25 of the ring 19 rests upon the sections 22 of the blocks, while the horizontal flange is supported by the substantially wedge-shaped sections 23 of the blocks. rlhe sections 23 of the blocks are attached to the sections 22 and to the beams 17 and struts 18 by nails 26, or by other suitable fastening means. Inasmuch as the inner face of the flange 25 of the ring abuts against the block sections 23, the said ring is held fiXedly in position upon the scaffolding.

The operation of this device is as follows: In erecting the column mold, first the scaffolding 1G is built. The blocks 21 are then attached to the beams 17 and struts 18 thereof. After this operation, the supporting ring 19 is placed in position, the ring being inserted from above the scaffolding. The column-top mold 10 is their inserted from abo/ve, whereby its flange 15 will rest upon the ring 19; The wedge-shaped section-s k523 of the blocks 21 are of such dimensions as to center the mold 10 in relation to the scaffold-- ing, as appears clearly from Figs. 2 and 4 ot the drawings, the inner top edges of vthe block sec-tions 3 abutting against the col umn mold, thereby holding the latter in position against lateral shifting. Ceiling mold plates 27 are then placed upon the scaffolding'. These pliates are secu-red tothe scaffolding in any suitable man-ner and extend tov the supporting ring 19. rllhe operator proceeds then with the molding operation in the usual manner, pouring Jche corr crete 28 into the mold 10 and on the top. ol? the ceiling mold plates 27.

After the column and ceiling have properly set, the blocks 21 are removed from the seaiiolding, permitting the supporting ring 19 to drop. The bolts 14: are then, by

means of a hammer or other suitable instru-v ment, broken, thereby' allowing the sections of the mold 10 to be taken apart and removed from. the finished column.

What we claim is:

l.. The combination with a scaffolding, of a sheet metal mold shaped to form the top of a column, said mold being provided with an outwardly bent flange at its upper edge, and a supporting ring upon said scaffold ing upon which said flange rests.

2. The combinati-on with a scaffolding, of a sheet metal mold shaped to form the top of a column, said mold being provided with an outwardly bent flange at its upper edge, blocks attached to said scaolding, and a supporting ring carried by said blocks, the flange of said mold resting upon said ring.

3. The combination" with a scaffolding, of a slt-.eet metal nro-ld shaped to form the top of a column, said mold being provided with outwardly bent flange at its upper edge, blocks` attached to said scaffolding,

and a supporting ring carried by said blocks,

the flange of' said mold resting upon said ring and said blocks abutting against the outer face of `said mold. y

4. The combination with a scaffolding, of a sheet metal mold shaped to forni the top of a. column, said meid being provided with an outwardly bent flange at its upper edge, a supporting ring, `and means for fixing said ring position upon said scaffolding, the flange ofsaid mold resting upon said ring.

5*. The combination with a scaffolding, of a sheet metal mold shaped to form the top of column, said mold being provided with outwardly ben-t flange at its upper edge, a supporting ring, and means for fixing said ring in position upon said seadolding, the flange 'of said mold resting upon said ring and said fixing means abutting against the outer face of said mold.
